Features |
| |
|
|
|
Easily usable lead frame shape with wide
resistance range. |
• |
Super-high precision resistors with resistance
tolerance  0.01% and T.C.R. 2.5×10-6/K. |
|
High density mounting available due to
its plate shape and thinness (t=2.5mm Max.). |
|
Excellent in long-term stability. |
|
Products meet
EU-RoHS requirements. |

Rated Ambient Temperature : +70
Operation Temperature Range : -55 +125
Rated voltage=√(Power Rating×Resistance value) or Max. working voltage, whichever is lower.
*1 Please consult with us for resistance other than E24 and E96.
*2 MRS1/3 is available only in E96 series. |

 |
|
|
For resistors operated
at an ambient temperature of 70 or above, a power
rating shall be derated in accordance with the left derating
curve. |
