Key Features

• Chip‑type, Surface‑Mount Package Radial, can‑style SMD package tailored for high‑density PCB layouts and automatic tape‑fed assembly.
• Bi‑Polar Construction Bi‑polarized capacitor suitable for circuits where polarity may reverse during operation.
• Electrical Performance 1 mF capacitance with 16 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Wide Operating Temperature Specified for operation from −55 °C to +105 °C to support temperature‑variable environments.
• Endurance and Lifetime Rated for 2000 hours at 105 °C (with polarity inversion every 250 hours as part of the endurance test).
• Ripple Current Capability Rated ripple current of 670 mA at 120 Hz and 770.5 mA at 10 kHz (frequency coefficients provided in the series datasheet).
• Board Landing Footprint Surface mount land size recommended: L: 1.83 × W: 1.83 cm, simplifying PCB layout and placement accuracy.
• Regulatory Compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑density PCBs — Designed for surface mounting and tape‑fed automatic assembly where board space and pick‑and‑place compatibility matter.
