Tecate releases PET/PP film capacitors

The polyester (PET) film Type 9114 and polypropylene (PP) film Type 9014 capacitors are claimed to eliminate the risk of short-circuit failure and are supplied with voltage options of 250VDC, 450VDC and 450VDC/220VAC.

A range of capacitance values and case sizes is also available to provide engineers with maximum design flexibility.

The RoHS-compliant, non-inductive parts feature self-healing properties to support long product life and are flame retardant epoxy resin coated.

Tecate's segmented metallised film Type 9114 and Type 9014 capacitors are designed to function in a range of active filter circuits in which high capacitance stability, dielectric absorption and self-healing performance is required.

They are commonly specified for use in converters and switch-mode power supplies (SMPSs) for laptop and desktop computers, as well as for industrial equipment.

The PET Type 9114 capacitors feature 17 capacitance options in a range from 0.1 microfarad to 10 microfarads and voltage options of 250VDC or 450VDC.

They are provided in sizes ranging from 5.5mm x 12.5mm x 9.0mm, up to 17.5mm x 31.0mm x 26.5mm.

Featuring a very high DV/DT value and a voltage of 450VAC/220VAC, the PP Type 9014 capacitors are available in 11 capacitance options ranging from 0.15 microfarad to 3.3 microfarads.

These parts may be ordered in sizes ranging from 5.5mm x 18.0mm x 9.5mm, up to 16.0mm x 31.0mm x 24.0mm.

Both the PET Type 9114 and PP Type 9014 are rated for an operating temperature range of -40C to +85C with full rated voltage applied.

Capacitance tolerances are +/-5 per cent, +/-10 per cent and +/-20 per cent.

The dielectric strength is 1.6Vr for two seconds and the dissipation factor is 1.0 per cent maximum at 1KHz at 25C.
