Product Feature
Product Advantages
Factory direct supply ensures competitive pricing with no middlemen. The 3214J features low CRV (≤3%R or 3Ω) and high stability over a wide temperature range (-55°C to +125°C). 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, this trimmer is ideal for volume orders. OEM and ODM services are available for custom requirements.
Applications
This trimmer is widely used in industrial control systems (automation equipment, robotics) for fine-tuning sensors and control loops. It serves test and measurement equipment (oscilloscopes, signal generators) for calibration. In medical devices (diagnostic tools, patient monitors), it ensures precise parameter setting. Communications equipment (RF devices, telecom infrastructure) uses it for signal matching. Automotive electronics (ECUs, dashboards) benefit from parameter optimization. Consumer electronics (audio devices, gaming consoles) rely on it for volume and sensitivity adjustment.
Key Features
4mm square SMD package with standard trimmer footprint
Multi-turn cermet element for high precision
Sealed to withstand board wash processing
Pick-and-place centering design with flush adjustment
Low contact resistance variation (≤3%R or 3Ω)
Operating temperature range: -55°C to +125°C
Temperature coefficient: ±100 or ±250 ppm/°C
Mechanical life: 200 cycles with ΔR≤±3%R
Packaging
Packaging specification: 500 pieces per reel (7-inch reel) or 1500 pieces per reel (13-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.
