Littelfuse Class T Fuse Blocks 300 600 Volt handbook
118 Class T Fuse Blocks 300 and 600 Volt SPECIFICATIONS include voltage ratings, ampere ratings, approvals, rated wire size, ampere rating, number of poles, catalog number, and connector type.
Littelfuse Axial Lead Cartridge Fuses handbook
This document describes the features and characteristics of Axial Lead and Cartridge fuses, including electrical characteristics, certifications, and interrupting rating.
Littelfuse DHB34 Varistor Series handbook
DHB34 series are industrial high-energy Metal-Oxide Varistors (MOVs), designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. DHB34 applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications. The DHB34 Series provides rigid terminals for through-hole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting.
Littelfuse HA Varistor Series handbook
HA Series transient surge suppressors are industrial high energy metal-oxide varistors (MOVs). They are designed to provide secondary surge protection in the outdoor and service entrance environment (distribution panels) of buildings, and also in industrial applications for motor controls and power supplies used in the oil-drilling, mining, and transportation fields.
Littelfuse AUML Varistor Series handbook
The AUML Series of Multilayer Transient Surge Suppressors was specifically designed to suppress the destructive transient voltages found in an automobile. These transient voltages are commonly caused by large inductive energy discharges. The AUML suppressor is manufactured from semiconducting ceramics, offering rugged protection and excellent transient energy absorption. The series is suitable for temperature ranges from -55°C to 125°C, providing temperature-independent suppression characteristics. The AUML suppressors are available in ceramic leadless chip form, eliminating lead inductance and ensuring fast response to transient surges. Compared to silicon TVS diodes, these suppressors require smaller space and land pads, providing greater flexibility in circuit board layout for designers.
Littelfuse ML Varistor Series handbook
ML Varistor Series is a family of Transient Voltage Surge Suppression devices based on Littelfuse Multilayer fabrication technology. These components are designed to suppress a variety of transient events, including those specified in IEC 61000-4-2 or other standards used for Electromagnetic Compliance (EMC).
Littelfuse MLE Varistor Series handbook
The MLE Series is a family of Transient Voltage Suppression devices based on Littelfuse's multilayer fabrication technology. These devices are designed to suppress ESD events and protect integrated circuits and other components at the circuit board level. They have capacitance characteristics suitable for high frequency attenuation/low-pass filter circuit functions, providing suppression and filtering in a single device. Manufactured from semiconducting ceramics, they are supplied in a leadless surface mount package. They are compatible with modern reflow and wave soldering procedures.
littelfuse Transient Voltage Surge Suppressor CH Varistor Series handbook
CH series transient surge suppressors are small, metal-oxide varistors (MOVs) manufactured in leadless chip form. They are intended for use in a variety of applications from low voltage DC to off-line board-level protection. These devices, which have significantly lower profiles than traditional radial-lead varistors, permit designers to reduce the size and weight and increase the reliability of their equipment designs. CH series varistors are available in a voltage range from 14V to 275V VM(AC)RMS , and energy ratings up to 23J. See the Littelfuse Multilayer Suppressor Series also.
Littelfuse ZA Series handbook
ZA Series Radial Lead Metal-Oxide Varistors for Low to Medium Voltage Operation
Littelfuse HB34 Vatistor Series
The HB34 Series is an industrial high-energy metal-oxide varistor (MOV) designed to provide surge suppression in the AC mains outdoor and service entrance environment of buildings. It is suitable for industrial heavy motors, controls, and power supplies used in the oil-drilling, mining, and transportation fields, as well as HVAC and motor/generator applications.
Littelfuse TMOV iTMOV Varistor Series
The Littelfuse TMOV and iTMOV varistors are integrated circuit protection devices that provide quick thermal response and low inductance. They are designed to protect against overheating caused by abnormal over-voltage and limited current conditions. The iTMOV varistor includes a third lead for indicating disconnection from the circuit. These varistors are wave solderable, simplifying product assembly. They are recognized surge suppression components to UL 1449.
