Product Overview
2E332M is a radial-lead X2Y EMI filter capacitor rated 332pF at 250V with +/-20% tolerance. The X2Y architecture provides broadband EMI filtering and decoupling through an integrated internal structure that delivers ultra-low equivalent series inductance - a performance level not achievable with a standard MLCC in the same footprint. Blue disc body, two straight radial wire leads, RoHS marked. Brand is unconfirmed; all specs are from seller notes and confirmed photo markings.
Key Features
- Capacitance: 332pF
- Voltage rating: 250V
- Tolerance: +/-20%
- Mounting style: Radial lead, through-hole
- X2Y integrated passive architecture - low ESL, broadband filtering
- RoHS compliant marking visible on body
- Blue ceramic disc body, approximately 15mm diameter per caliper measurement in photos
- Markings confirmed: 2E332M, X2Y, 250V, Y12V, triangle logo
Applications
- PCB designers integrating this into layouts where a conventional MLCC or discrete filter network is failing EMI compliance - the X2Y geometry replaces multiple components and tightens the ground path in one footprint
- Repair technicians swapping a failed X2Y filter on a motor drive, audio amplifier, or industrial control board where restoring the original filter topology matters for noise performance
- Engineers decoupling power rails on FPGAs, ASICs, or microprocessors where high-frequency switching noise demands lower inductance than a standard bypass cap can provide
- Makers and experimenters building low-noise power supplies or audio circuits who want to explore X2Y filtering on through-hole prototype boards before committing to a surface-mount layout
Frequently Asked Questions
What is the mounting style - through-hole or surface mount?
Through-hole, radial lead. Two straight wire leads extend from the ceramic disc body. Most X2Y capacitors on the market are surface-mount chip devices, which makes this radial-lead version a less common form factor for the X2Y architecture.
What is the manufacturer or brand?
Brand is unconfirmed. The part number 2E332M and X2Y marking are visible on the body, but no manufacturer name or logo has been identified. Photos show a triangle logo on the body; the specific maker has not been confirmed.
Is a datasheet available for this part?
No datasheet is included. The confirmed specifications are those visible on the part itself and noted by the seller: 332pF capacitance, 250V rating, +/-20% tolerance, radial lead mounting. Dielectric type and ESR are not confirmed.
What are the physical dimensions?
Caliper measurement visible in the product photos shows the ceramic disc body at approximately 15mm in diameter by approximately 3mm thick.
The through-hole X2Y in a sea of surface-mount parts - it is a narrower shelf to shop, which means if this is the form factor your board needs, you already know it. The leads are clean, the markings are clear, and it is ready to go to work.
