Product Feature
Product Advantages
Factory direct supply ensures competitive pricing with no middlemen. The 3313J-1 features low CRV (≤3%R or 3Ω) and high stability over a wide temperature range (-55°C to +125°C). It offers 0.125W power rating at 70°C, with 250° total mechanical travel and 220° electrical travel, providing smooth and stable adjustment feel. It boasts completed certificates like RoHS and REACH, guaranteeing quality assurance. With sufficient production capacity and short delivery times (within 15 workdays), plus professional after-sales support, OEM and ODM services are available.
Applications
This trimmer is widely used in audio equipment (sound systems, mixers) for tone and volume adjustment. It serves consumer electronics (smart home devices, portable gear) for parameter setting. In industrial controls (PLCs, automation equipment), it enables circuit calibration. Power supplies rely on it for output voltage fine-tuning. Measurement and testing instruments (multimeters, signal generators) use it for accuracy. Other applications include robotics, automotive electronics (ECUs, sensors), and telecommunications equipment.
Key Features
3mm square ultra-miniature SMD package saves PCB space
Single-turn cermet element for quick adjustment
Top slot adjustment for easy integration
Sealed to withstand board wash processing
Low contact resistance variation (≤3%R or 3Ω)
Operating temperature range: -55°C to +125°C
Temperature coefficient: ±100 or ±250 ppm/°C
Rotational life: 100 cycles with ΔR≤±3%R
Packaging
Packaging specification: 1000 pieces per reel (7-inch reel). The trimmer is shipped in anti-static, environmentally friendly materials compliant with RoHS standards. Each reel is labeled with model number, quantity, and date code. Custom packaging options are available upon request.
