상품 특징

• Specs & cross-refs (verify on board before ordering): UD2 series, DPDT (2 Form C), 12 VDC coil, 1 A resistive @ 30 VDC (UL), up to 125 VAC/0.5 A and 110 VDC/0.3 A per safety listings; SMD gull-wing 8-pin package; miniature footprint 10.6 × 6.5 × 5.45 mm; typical coil current ≈11.7 mA, power ≈140 mW. Compatible with KEMET/NEXEM/NEC UD2-12NU footprints; THT counterpart UC2-12NU; low-power and min-footprint variants UD2-12NE / UD2-12NUN. Always match coil voltage, footprint, and contact form to your board design
• Installation & location guidance: Designed for surface-mount reflow on printed circuit boards (not a blade/fuse-box relay). Observe polarity/markings, orientation dot, and pad layout from the datasheet; follow standard reflow profile and cooling guidance; handle with ESD care. Typical board locations include electronic switching equipment, PBX/telephony, terminal equipment, instrumentation, alarms/IoT controllers, or electronics repair where the silkscreen/part list calls UD2-12NU
• What issues it helps address (board repairs): Replaces failing signal relays that cause intermittent line switching, stuck contacts, no changeover on low-power control paths, crosstalk or channel drop-outs on telecom/control PCBs. The DPDT contacts provide two changeover paths for reliable A/B routing or control logic isolation in low-power circuits. Verify the load is within the listed resistive ratings and derate appropriately
• Compliance & reliability details: UL Recognized (UL508 E73266), CSA Certified (LR46266), TUV (EN61810); RoHS compliant. Typical mechanical endurance up to 10⁷ operations (ref. series data), compact, low magnetic interference design for dense mounting. Use proper snubber/diode across the coil if your design requires suppression
• Complementary/alternative options to capture related needs: For boards needing other coil voltages use UD2-3NU / UD2-4.5NU / UD2-5NU / UD2-9NU (same series), or consider UC2-12NU when a through-hole drop-in is specified. For reduced coil power, match footprint with UD2-xxNE variants. These are series-level, footprint/voltage alternatives—select strictly by your board’s BOM and datasheet. Compatible with the corresponding UC2/UD2 series footprints from major manufacturers.
