Product Advantages
Factory direct with RoHS certification. Single‑turn design with multi‑finger wiper ensures ΔR≤±3%R after 200 cycles. Sealed body withstands washing and reflow soldering. Operating temperature -55°C to +125°C, dielectric strength 500Vac (1 min.). Standard tolerance ±20% or ±25% meets general calibration needs. Cermet element provides long‑term stability.
Product Features
3mm square, SMD package
Top cross‑groove adjustment (small screwdriver)
Single‑turn, 220° electrical travel, 250° mechanical travel
Cermet resistive element, multi‑finger wiper
Sealed construction – washable
RoHS compliant
Applications
Ideal for: Portable electronics (Bluetooth headsets, smartwatches), power modules (DC‑DC converters), instruments (digital multimeters, thermometers), communication devices (routers, two‑way radios), consumer electronics (LCD contrast calibration, audio gain control), automotive electronics (sensor trimming), industrial controls (PLC analog calibration). Used for factory presets and field circuit trimming.
