RATING THERMAL SENSORS CIRCUIT PROTECTORS Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use. Pb-free Part No. NV Enter disc diameter *2 Manufacturing range of NVD10UBC is varistor voltages 22...270. *3 NVD14C100 is applied. Use the varistor within the specified values as there is a risk of destruction of the varistor when the impulse power over the maximum energy is applied.
