Additional Details

The RD3A2BY105J-T2 resistor has a resistance value of 1.0 MΩ (105 = 10 x 10^5 ohms). The 'T2' likely refers to the packaging (tape and reel). The power rating is dependent on the package size and should be confirmed with the KOA Speer datasheet. Typical specifications found on the datasheet will include resistance tolerance (e.g., ±5%), temperature coefficient of resistance (TCR), voltage rating, and operating temperature range. The operating temperature range for KOA Speer thick film resistors is typically -55°C to +155°C. Always consult the official KOA Speer datasheet for the RD3A series to determine the exact electrical characteristics and physical dimensions of this specific resistor.
