• The RC network will suppress arcing and also reduce dv/dt
• RFI can be reduced over a wide frequency range
• Capacitor and resistor are connected in series
• Metallised Polyester
• 250V AC rated
• UK manufactured

Sudden interruption of current in an inductive circuit normally produces a high voltage surge. Damage to contacts occurs due to arcing. In thyristor or Triac Circuits incorrect functioning may result due to high dv/dt. The LCR RC network will suppress arcing and also reduce dv/dt. The RC network also suppresses radio interference over a wide frequency range.
Specifications:
Capacitance 0.1µF
Resistor 100Ω
Maximum Voltage 250Vac (class x)
Power Rating 0.5 W
Terminations 0.8mm tinned copper wire
Dimensions 22 x 8 x 19mm (Lead spacings 22.5mm)
Rated 4 out of 5 by from Solving sticky Contacts I had relay contacts sticking together due to sparking thus the equipment stayed on. This removed the spark thus contacts with clean break.

I have replaced two lamps for LED units but they continue to glow slightly even when switched off and having looked for solutions several people are recommending that fitting this unit will resolve the issue. Is this true? Where/how would it be installed?

Does this just connect between love and switch live in the light fitting or switch?  A qualified electrician will be installing but just want him to get it right Thanks

Asked by: Terry
This would normally be used on the live line yes, but we are not electricians so would not be able to advise where to use this on a mains electrical system.

How do you actually install this? My leds flash when off, and I have a dimmer switch. I know the problem but I have no clue how to install these.

Asked by: samuel11
We cannot advise how to actually install this item as tampering with mains electrical can be dangerous, we would advise if unsure to contact a qualified electrician. The Suppressor itself uses a simple in out design. Which would not matter if used on the Live or Negative line if used on a AC circuit.
