Vishay Extends 140 CRH Series of SMD Aluminum Capacitors to Provide High Capacitance Values up to 1000 μF, High Ripple Currents to 900 mA at 125 °C, and Low ESR Down to 90 mΩ
Devices Offer Long Life to 3000 Hours at +125 °C and 4-Pin Versions For High Vibration Capability
MALVERN, PENNSYLVANIA — August 1, 2008 — In a move to meet the demands for performance and reliability in automotive and industrial systems, Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended the capabilities of its 140 CRH series of surface-mount aluminum capacitors to offer very high capacitance values and ripple currents.
A polarized aluminum electrolytic capacitor with a non-solid, self-healing electrolyte, the 140 CRH is ideally suited for filtering, smoothing, buffering, and voltage decoupling applications in automotive and industrial systems for high ambient temperatures up to 125°C.
Offering enhanced performance and reliability, the devices feature a capacitance range of 10 μF to 1000 μF over a voltage range of 6.3 V to 63 V, a high ripple current up to 900 mA at 100 kHz/125 °C, and ESR down to 90 mΩ at 100 kHz. The capacitors are available in five case sizes, ranging from 8 mm by 8 mm by 10 mm to the larger 12.5 mm by 12.5 mm by 16 mm.
For high vibration capability, 140 CRH capacitors with 12.5-mm diameters are available in 4-pin versions, with 4-pin versions of 10-mm devices available on request. The capacitors feature a long life up to 3000 hours at +125 °C.
The RoHS-compliant devices are charge- and discharge-proof, so there is no peak current limitation. The capacitors operate over a broad temperature range from -55 °C to +125 °C.
Samples and production quantities of the 140 CRH SMD aluminum capacitors are available now, with lead times of 15 weeks for larger orders.
