LITTELFUSE Manuals

This document describes the features and characteristics of Axial Lead and Cartridge Fuses 406, including material, electrical characteristics, certifications, and interrupting ratings.

This document describes the features of Littelfuse's silicon avalanche diode products, including the packaging method, breakdown voltage range, glass passivated junction, excellent clamping capability, low zener impedance, etc.

1N60 series are small, high-power transient voltage suppressors with excellent clamping capability, low zener impedance, and can withstand up to 15000 watts of shock pulses. They can still work normally at extremely low temperatures.

This document describes the characteristics of 378 surface mount fuses, including their nominal current, nominal voltage, cold resistance, and melting I2t values. These fuses comply with the IEC 60127-4 standard, are certified by UL, METI, and CCC, and have high environmental adaptability.

233 series medium-acting fuses, UL/ CSA/ANCE 248 standard, rated current 1-10A, RoHS and Lead-Free version available

The document describes a Shock-Safe fuseholder for PCB mounting, suitable for 3AG or 5x20mm fuses. The fuseholder complies with IEC 60127 and 60065 standards and comes with two different knob styles. Approvals include UL 16A 250V, CSA 15A 250V, and VDE 10A 250V.

Littelfuse fuse reducers allow smaller size fuses to be installed into existing fuse clips. This prevents overfusing. They allow lower ampere-rated fuses to be used in existing fuse clips. They are simple to install, reduce inventory requirements, and have silver brazed joints for maximum strength.

The datasheet provides the specifications of Littelfuse SIDACtor devices, including rated voltage, rated current, maximum surge current, surge energy, failsafe level, etc.

BZY91C is a type of Zener diode from Littlefuse with a rated voltage of 7.5-75 volts, 5000 watt peak pulse power, 100 watt steady state power (25°C), 75 watt steady state power (65°C), 5000 watt surge capability (1ms), typically IR less than 1µA above 10V, excellent clamping capability, stud cathode and stud anode, operating temperature -55°C to +175°C, 100% tested

This is a 1500W surface mount transient voltage suppressor that features RoHS compliance, is suitable for surface mount applications to optimize board space, has a low profile package, built-in strain relief, glass passivated junction, low inductance, excellent clamping capability, repetition rate (duty cycle) of 0.05%, fast response time (typically less than 1.0ps from 0 Volts to BV min.), typical IR less than 1µA above 10V and high temperature soldering (250℃/10 seconds at terminals).

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 (TVSS), Uninterruptable Power Supplies (UPS), 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. These devices are produced in radial lead package sizes of 7, 10, 14, and 20mm and offered in a variety of lead forms. UltraMOVs are manufactured with recognized epoxy encapsulation and are rated for ambient temperatures up to 85oC with no derating. This Series is LASER-branded and is supplied in bulk, ammo pack (fan-fold), or tape and reel packaging.

The MA Series is a range of axial-lead metal-oxide varistors (MOVs) designed for use in board level industrial and commercial electronic equipment. They are used to protect components and signal/data lines from low energy transients. The MA Series is available in a small axial lead package and offers standard or tightened clamping voltage options.
