The KEMET Fail-Safe Floating Electrode MLCC/FE-CAP utilizes floating internal electrode design, where electrodes form capacitors in single MLCC packages. Improved voltage and ESD performance over standard designs lower risk of low-IR or short-circuit failures that may occur due to board flex.
New! KEMET has expanded the T513 COTS Capacitor Series to include additional caps rated at 35V.
KEMET T513 Multiple Anode MnO2 Series Capacitors are
ideal for the Commercial-Off-the-Shelf (COTS) needs of the aerospace,
communications, military, and industrial markets. Features of the
highly reliable T513 Series COTS Capacitors from KEMET include
capacitance values of 68µF to 1,000µF, voltage rating of 4VDC-35VDC,
ESR as low as 12mΩ, high surge current capability, and high ripple
current capability. The T513 series has a multiple anode construction
similar to KEMET's T510 Series.
KEMET T488 Series Small Case Size Surface Mount Tantalum Capacitors use a substrate termination design, which results in one of the highest volumetric efficient packaging technologies available today in tantalum chip capacitors. The T488 series surface mount tantalum capacitors from KEMET offer 220µF capacitance and 4V voltage in the small EIA 2012-12 case size. This series is ideal for densely populated circuits such as smart phones and digital cameras where space restrictions do not allow for larger and more commonly available case sizes.
KEMET T527 Series Facedown Terminal Polymer Tantalum KO-CAPs (Organic Capacitors) have a Ta anode and Ta2O5 dielectric and conductive organic polymer that replaces the traditionally used MnO2 as the cathode plate of the capacitor, resulting in very low ESR and improved capacitance retention at high frequency. The T527 Series Polymer Tantalum KO-CAPs from KEMET offer improved packaging efficiency with a low profile design through the use of facedown technology. This series offers high capacitance from 22-100µF and voltage range from 4-10V in a 3216-10 package size and is ideal for densely populated circuits where space restrictions do not allow the use of more commonly available, larger sized components.
KEMET High Voltage surface mount Multilayer Ceramic Chip
Capacitors (MLCCs) in X7R dielectric offer industry-leading CV values
(capacitance/voltage) with voltage range from 500 VDC to 3,000 VDC.
Advances in KEMET's base-metal-electrode (BME) high voltage X7R
technology have led to the development of some of the highest
capacitance values available in the industry, including first-to-market
values. Available capacitance has been increased in EIA 1206 through
2225 case sizes and in rated voltages of 630 VDC through 3,000 VDC. The
High Voltage SMD X7R MLCCs from KEMET exhibit low leakage current, low
ESR, and exceptional performance at high frequencies, making them the
ideal choice for design engineers globally.
KEMET T529 Series Polymer Tantalum Capacitors are part of the KO-CAP product line in which a conductive organic polymer replaces the traditionally used MnO2 as the cathode plate of the capacitor, resulting in very low ESR and improved capacitance retention at high frequency. The T529 Series KO-CAP from KEMET uses a substrate termination design, which results in the most volumetrically efficient packaging technology available today in polymer tantalum chip capacitors. T529 Series capacitors offer high capacitance values (22µF to 150µF) in a small 2012 case size and are ideal for use in densely populated circuits such as smart phones and digital cameras where space restrictions do not allow for larger and more commonly available case sizes.
NEW! KEMET has expanded the T550 Polymer Hermetic Seal Capacitor series (PHS)
to now include 75V capacitors. These newest T550 PHS caps from KEMET
offer the highest voltage and deliverable energy with the lowest DC
leakage and ESR in the industry, as well as the highest ripple current
capability in its class.
KEMET T550 Polymer Hermetic Seal Series (PHS) is a tantalum capacitor with a Ta anode and Ta2O5 dielectric with a conductive organic polymer that replaces the MnO2
or wet electrolyte traditionally used as the capacitor's cathode
plate. The organic polymer characteristic of the T550 Polymer Hermetic
Seal Series (PHS) from KEMET results in very low ESR and improved
capacitance retention at high frequency and low temperature. The T550
PHS capacitor can be operated at voltages up to 80% of rated voltage
with equivalent or better reliability than the traditional MnO2
or wet tantalum capacitors that operated at 50% of rated voltage. The
capacitance range of the T550 tantalum capacitor is 100µF to 120µF @ 120
Hz/25ºC and its operating temperature range is -55ºC to 105ºC.
The KEMET High Voltage Flexible Termination (HV FT-CAP) MLCCs are SMT commercial grade X7R capacitors that combine high voltage and flexible termination technologies in order to address the primary failure mode of MLCCs - flex cracks. Flexible termination
technology directs board flex stress away from the ceramic body and
into the termination area, therefore mitigating flex cracks which can
result in low IR or short circuit failures. The KEMET High Voltage Flexible Termination (HV FT-CAP) MLCCs feature a 125ºC maximum operating temperature to be considered "temperature stable", a broad range of capacitance requirements,
low leakage current, low ESR at high frequencies, up to 5mm of flex-bend capability, and a predictable change in
capacitance with respect to time and voltage. The HV FT-CAPs are available in DC voltage ratings of 500V,
630V, 1KV, 1.5KV, 2KV, 2.5KV, and 3KV and capacitance offerings from 100pF to 0.1µF. The KEMET HV FT-CAP's exceptional performance at high frequencies and high voltage has made them a preferred choice for use in power supplies and industries such as telecommunications, medical, military, aerospace, semiconductors, and test/diagnostic equipment.

Flexible Termination technology utilized in several series of KEMET surface mount multilayer ceramic chip capacitors (MLCCs) was developed to address flex cracks, the industry's primary failure mode for MLCCs. Flexible termination directs circuit board stress away from the ceramic body and into the termination area, reducing the risk of mechanical damage to the component that can result in low IR and short circuit failures.
