Panasonic ERA-3EEB7321V Resistor Metal Film - SMD Thin Film Resistor
The Panasonic ERA-3EEB7321V is a high-reliability metal film chip resistor designed for surface-mount applications. Manufactured in the US, this resistor offers precise resistance values with excellent thermal stability and low noise characteristics, making it suitable for a wide range of electronic circuits requiring stable and accurate resistance components.
Product Features
Small size and lightweight for space-constrained designs
High reliability with low temperature coefficient of resistance (T.C.R.) and minimal current noise
Suitable for both reflow and flow soldering processes
The first two digits represent significant figures, and the third digit indicates the number of zeros following. For example, a resistance value of 100 corresponds to 10 ohms.
ERA3Y: 5000 pcs./reel ERA6Y: (Quantity not specified)
Recommended Land Pattern
For reflow soldering, land width should be 0.7 to 0.8 times the resistor width (W). For flow soldering, set land width to 1.0 to 1.3 times W to ensure proper soldering and mechanical stability.
Soldering Conditions
Preheat temperature: 140°C to 180°C for 60-120 seconds
Soldering temperature: 245°C ± 5°C for 20-30 seconds (max 260°C)
Safety Precautions
Operate within rated power and temperature derating curves.
Evaluate resistor performance under transient loads before use.
Avoid using high-activity fluxes that may impair performance.
Minimize mechanical stress during mounting and handling.
Do not expose resistors to long-term solvents or mechanical shocks.
For detailed technical specifications, please refer to the datasheet.
