jb Capacitors have introduced the JFZ series of X2 interference suppression, metalised polyester film, capacitors.
A rated mains voltage of up to 310Vac allows the JFZ series to be used with 277Vac
nominal inputs, prevalent in the US market for lighting, in addition to 115Vac and 230Vac nominal
mains voltages. This makes the JFZ series ideal for a significant number of applications including
power supplies, lighting ballasts, LED lighting, control devices and instrumentation.
The RoHS compliant series is available in industry standard capacitance values ranging from 2200 pF
to 2.2 µF, with a standard tolerance of ±10%. Safety certifications have been granted by VDE and
ENEC for Europe and UL/cUL for North America to the IEC/EN/UL 60384-14 standard. X2 capacitors
can be used continuously between line and neutral, and are designed to fail safe in an open circuit
condition, rather than short circuit, to prevent hazards. The non-inductive capacitors are enclosed in
a UL94V-0 plastic case sealed with epoxy resin, and will operate over a wide -40ºC to 110ºC
The JFZ series represents an improvement over the previous JFV series, with lower pricing and
improved lead-times of just 5 to 7 weeks ex-factory (MOQ 5,000 pieces). The maximum operating
voltage, which has been enhanced from 275Vac to 310Vac, also gives the design engineer additional
margin for reliability.
