Product Overview
The TDK CS472M is a safety-rated ceramic disc capacitor designed for AC line filtering and transient suppression. Rated for 4700 pF (4.7 nF) with a ±20% tolerance, this radial-lead component carries Class Y agency certifications for line-to-ground isolation barriers and mains noise filtering across demanding power circuits.
Key Features
- 4700 pF (4.7 nF) nominal capacitance with ±20% tolerance (M code)
- Safety rated for 400 VAC applications (Class Y)
- Agency approval markings: VDE (560-2, 565-1), UL Recognized component mark, SEMKO, DEMKO, FIMKO, and SEV
- Straight radial wire leads for through-hole PCB mounting
- Durable flame-retardant orange epoxy disc coating
- Climatic rating mark: EW1~
Applications
- Replacing failed line-to-ground safety capacitors in switch-mode power supplies and vintage audio gear
- Mains EMI and RFI suppression at line entry points on industrial controls and test equipment
- Line noise bypass and isolation filtering for custom bench power supplies and maker projects
Frequently Asked Questions
What is the lead spacing on this capacitor?
Lead pitch is approximately 10 mm with straight wire leads extending roughly 35 mm from the base of the disc.
Can this capacitor be used in line-to-ground AC filtering?
Yes. The CS series carries Class Y safety certifications and 400 VAC rating specifically intended for line-to-earth and isolation barrier applications.
Why buy individual capacitors here instead of a bulk surplus grab bag?
You receive the exact TDK safety capacitor shown, with verified markings and intact leads, without having to purchase a full factory reel or sort through mixed surplus grab bags. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, qualify for free shipping at $28 or more, and leave our Idaho warehouse the same or next business day.
When line-level transients hit your power rail, a solid safety ceramic is the quiet guardian that takes the hit and protects the rest of the bench.
