Littelfuse


LA Series Image
  • Energy Absorption Capability
  • Wide Operating Voltage Range
  • Available in Tape and Reel or Bulk Pack
  • RoHS Compliant
The LA series of transient voltage surge suppressors are radial leaded varistors that are designed to be operated continuously across AC power lines. These UL recognized varistors require very little mounting space, and are offered in various standard lead form options.
ZA Series Image
  • Wide Operating Voltage Range
  • 5 Model Sizes Available
  • Standard Lead Form Options
  • Available in Tape and Reel or Bulk Pack
  • RoHS Compliant
The ZA series of transient voltage surge suppressors are radial leaded varistors designed for use in the protection of low and medium-voltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity.
C-lll Series Image
  • High Energy Absorption Capability
  • High Pulse Life Rating
  • High peak Pulse Current Capability
  • Wide Operating Voltage Range
  • RoHS Compliant
The C-lll series of metal oxide varistors are specifically designed for applications requiring high surge energy absorption ratings and superior multiple pulse absorption rating. This is achieved through a special dielectric material formulation which also results in higher repetitive surge ratings than other MOV types.
iTMOV Series Image
  • Patented Integrated Thermal Protection Device
  • Wave Solderable
  • Low Leakage
  • Standard Lead Form and Spacing Option
  • RoHS Compliant
The Littelfuse TMOV and iTMOV thermally protected varistors represent a new development in integrated circuit protection. Both versions are comprised of radial leaded MOVs with integrated thermally activated element designed to open in the event of overheating due to the abnormal overvoltage limited current. They offer quick thermal response due to the close proximity of the integrated thermal element to the MOV body. The integrated configuration also offers lower inductance than most discrete solutions resulting in improved clamping performance to fast overvoltage transients
RA Series Image
  • Wide Operating Voltage Range
  • High Energy Absorption Capability
  • 3 Model Sizes Available
  • Low Profile Outline with Precise Seating Plane
  • RoHS Compliant
The Ra series transient surge suppressors are varistors supplied in a low profile box that features a precise seating plane to increase mechanical stability for secure circuit board mounting. This feature makes these devices suitable for industrial applications critical to vibration. Their construction permits operation up to 125 degrees Celsius without derating.
TMOV Series Image
  • Patented Integrated Thermal Protection Device
  • Wave Solderable
  • Low Leakage
  • Standard Lead Form and Spacing Option
  • RoHS Compliant

TMOV25S Series Image
  • Patented Integrated Thermal Protection Device
  • Wave Solderable
  • Low Leakage
  • Standard Lead Form and Spacing Option
  • RoHS Compliant
The Littelfuse TMOV24S series was designed to address this condition in a single integrated package. The TMOV25S series incorporates a patented integrated thermally responsive element within the body of the device which will open-circuit the varistor in case of overheating due to the abnormal over voltage events.
UltraMOV Series Image
  • Standard Lead Form and Lead Space Options
  • Custom Voltage Types Available
  • Characterized for Maximum Standby Current
  • RoHS Compliant
The UltraMOV metal oxide varistor Series is designed for applications requiring high peak surge current ratings and high energy absorption capability. UltraMOV varistors are primarily intended for use in AC line voltage applications such as transient voltage surge suppressors, uninterruptable power supplies, AC power taps, AC power meters, or other products that require voltage clamping of high transient surge currents from sources such as lightning, inductive load switching, or capacitor bank switching.
