POLYFUSE® Resettable PTCs  
Radial Leaded  
250R Series  
Description  
• The 250R series is designed to protect against short  
duration high voltage fault currents (power cross or  
power induction surge) typically found in telecom  
applications (250Vrms). The series can be used to help  
telecom networking equipment meet the protection  
requirements specified in ITU K.20 and K.21.  
Features  
• RoHS compliant and  
lead-free  
• Fast time-to-trip  
• 0.08 – 0.18 Hold current  
range, 60VDC operating  
voltage  
Agency Approvals  
• Binned and sorted narrow  
resistance ranges available  
• 250VAC interrupt rating
