Product Overview
Pilkor WK9611-X2 is a Class X2 safety-rated metallized polypropylene film capacitor built for across-the-line AC filtering. Box-style body, rated 275V AC, designed to suppress differential-mode EMI and RFI at the AC mains input stage. Self-healing metallized film construction and a flame-retardant case make it a dependable choice for both repair and new design work.
Key Features
- Class X2 safety rating - designed for line-to-line (across-the-line) AC mains applications
- 275V~ AC voltage rating
- Metallized polypropylene film (MKP) dielectric - self-healing construction
- Box-style housing with flame-retardant case
- Radial lead configuration - measured approximately 18mm body width per photo evidence
- Marked 1P M-275V~ X2 on body - confirmed from product photos
- Suitable for differential-mode EMI and RFI suppression
Applications
- Repair technician replacing a failed or bulging X2 capacitor in the AC input stage of a washing machine, HVAC unit, or vintage audio equipment - desolder the old part, drop this one into the across-the-line position, restore clean power
- Industrial maintenance tech swapping a degraded input filter capacitor in a switch-mode power supply or motor drive - de-energize the equipment, identify the failed X2, install and verify reduced noise and stable operation
- Product developer integrating a pre-certified EMI suppression component into a prototype AC-mains circuit, reducing the re-testing burden before regulatory submission
- Hobbyist repairing vintage electronics or consumer appliances where the original across-the-line capacitor has failed or shows visible damage
- Maker building a DIY mains filter or AC power conditioner where a safety-rated film capacitor is required across the line
Frequently Asked Questions
Is this an X2 or Y capacitor?
X2. It is designed for line-to-line (differential mode) filtering only. Do not use it in line-to-ground (Y-capacitor) positions - different safety requirements apply to that role.
What is the capacitance value?
The specific capacitance value is not marked on the visible face of this unit based on photo evidence. Buyers should confirm the capacitance value matches their application before ordering.
Will the lead spacing fit my PCB?
Lead spacing is not confirmed from the available information. The body measures approximately 18mm wide per the ruler visible in the product photos. Verify the footprint against your PCB layout before ordering.
Is this suitable for 120V and 240V mains circuits?
Yes. The 275V AC rating covers both 120V and 240V mains voltages used in residential and commercial applications worldwide.
Does this come with any certifications?
The body is marked as Class X2, confirming it meets the X2 safety class requirement for across-the-line capacitors. Specific certification marks (UL, VDE, CSA, ENEC, CQC) are not confirmed from available information.
The AC mains filter position is not the place to gamble on a generic substitute - the X2 rating is the line between adequate noise suppression and a real safety risk. This one has it. Clean leads, unused, and ready to go back to work.
