Low-ESR capacitors enable efficient filtering and energy storage

Vishay’s TR3 series of moulded tantalum chip capacitors provide Equivalent Series Resistance (ESR) values down to 0.035O and maximum ripple current values up to 2.07A (100kHz, 470µF).

Low ESR values allow for more efficient filtering n DC/DC conversion applications, while the devices’ ability to handle high currents is key in microprocessor bulk energy storage applications. In addition, the new tantalum capacitors feature a proven solid tantalum construction that ensures long-term reliability.

TR3 devices are available in five moulded case sizes from A to E and capacitance values from 0.47µF to 680µF at standard capacitance tolerances of ±10% and ±20%. Voltage ratings range from 4V DC to 50V DC. The operating temperature range for the new devices is -55°C to 85°C, or 125°C with voltage derating.

 

FEATURES Terminations: 100% Tin. Standard SnPb available Moulded case available in five case codes High ripple-current carrying capability Meets EIA 535BAAE and IEC specification QC300801/US0001
