Film capacitors withstand lead-free
reflow
A new range of surface-mount film capacitors are both RoHS-compliant and able to withstand the higher manufacturing temperatures of Pb-free soldering.
Acal Components has introduced a range of surface-mount film capacitors which are both RoHS-compliant and able to withstand the higher manufacturing temperatures of Pb-free soldering The new SMD-PEN and SMD-PPS surface-mount film capacitors are manufactured by Wima and can replace almost the full range of through-hole film capacitors, even in demanding applications

Batteries cover all the standards
A comprehensive range of standard and high-performance batteries is available in industry-standard case sizes.
The temperature-resistant PEN (polyethylennaphthalate) and PPS (polyphenylene-sulphide) metallised dielectric films offer an extremely high capacitance stability over changes in temperature and frequency.
The SMD-PEN series is rated for operation up to 125C and the SMD-PPS series for operation up to 140C.
A box-style construction gives additional protection against thermal and mechanical stress during manufacture and in the field compared with nonencapsulated or moulded alternatives.
Simon Rush, Divisional Director, Acal Components commented: "These capacitors are rated to withstand soldering bath temperatures up to 260C and are suitable for both wave and reflow soldering techniques".
"They are intended to replace through-hole devices in general DC applications such as bypass, blocking, timing, coupling and decoupling".
The series are available in 1210, 1812, 2220, 2824, 4030, 5040 and 6054 case sizes and cover capacitance values from 1000pF to 6.8uF with a range of rated voltages from 63 to 1000V DC.
