Paktron ST Surfilm Series

Paktron’s ST Surfilm® Series is a family of multilayer metallized polymer surface-mount film capacitors designed for compact, high-reliability electronic assemblies. Available in both chip-style and lead-frame-style configurations, the ST Series provides non-polarized capacitor performance in EIA chip sizes with Pb-free machined terminations and reflow solderable construction. The ST Surfilm® Series uses a non-inductive metallized polyester dielectric in a parallel plate multilayer polymer design, supporting stable film capacitor performance in a small surface-mount package. With capacitance values of 1.0 µF and 2.2 µF, 100 VDC / 80 VAC voltage rating, and an operating temperature range of -55 °C to +125 °C, the series is well suited for compact power electronics, filtering, and high-reliability surface-mount applications.
