The CWR11 series is Vishay Sprague's TANTAMOUNT® military solid tantalum chip capacitors that are rated for operation from -55°C to +85°C and have a voltage rating of 4 WVDC to 50 WVDC. These capacitors have a capacitance range of 0.10µF to 100µF and are available with ±20%, ±10% and ±5% tolerances. The CWR11 series capacitors are available in four different case codes and offer multiple termination and surge current options.
The Vishay CWR11 series provides solid tantalum chip capacitors ranging from 0.10 µF to 100 µF with voltage ratings from 4 V to 50 V. Features include molded case options, high‑volume pick‑and‑place compatibility, and a solder‑plate termination.
