Features
 
• Respondable to resistance tolerance 1% and T.C.R. 100 ×10-6/K.
• Resistors up to high resistance range in small sizes are available.
• Highly stable against environmental conditions and overload.
• The discharge path resistor is recognized by UL1676 and c- UL (CSA- C22.2 No.1- M94).(File No.E159326)
• Products meet EU-RoHS requirements.
EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass.
