Heat Sinks

H-Chip Aluminum Polymer capacitors provide a low profile surface mount (SMT) package. The main advantage of this capacitor design is the extremely low ESR and ESL. This is the reason why H-Chips are the perfect solution for input and output capacitors of SMPS.

H-Chips are a suitable alternative for tantalum capacitors and MLCC´s. In comparison to tantalum capacitors, there is no voltage derating related to rated voltage necessary and they are not flammable.

Compared to MLCC´s, H-Chips do not have a DC-Bias behavior. Furthermore, H-Chips offer a more stable temperature performance compared to Class 2 ceramics (e..g. X7R / X5R) and have a long lifetime performance.

H-Chips will be available in four different product series:

WCAP-PHGP: General Purpose

WCAP-PHET: Extended Temperature 125 °C

WCAP-PHLE: Low ESR

WCAP-PHSE: Super Low ESR

The main characteristics are:

Capacitance range: 15 µF up to 560 µF

Rated Voltage: 2 V(DC) up to 35 V(DC)

Temperature range: -55 °C up to 125 °C

Endurance: 1000 h up to 2000 h

ESR: 3 mΩ up to 40 mΩ

H-Chip Aluminum Polymer Capacitors are typically used in the following applications:

Input and output capacitors for SMPS

Noise suppression

DC/DC Converter

Mainboards

Telecommunication & base stations
