Product Categories
The catalogue covers various fuses, fuseholders, accessories, terminal blocks, switches, and thermal protections.

Fuse Specifications
Fuses are available in multiple sizes, including subminiature options. Common sizes are 5x20mm and 6.3x32mm. Selection is based on voltage rating, current load, and environmental conditions.

General Information
Fuses protect components and systems from overloads and short circuits. Correct fuse selection ensures safety and reliability in electronic circuits.

Color Code for Fuses
A detailed color code chart for fuses with current ratings from 32 mA to 6.3 A is provided.

Basic Fuse Technology
Miniature fuses protect against fire and shock risks from overcurrents and isolate subsystems from the main system during faults.

Selecting Overcurrent Protection
Consider voltage rating, full load currents, short circuit current, in-rush characteristics, equipment characteristics, ambient conditions, standards, board space, mounting type, reliability, and field service ease.

Voltage Ratings
The fuse's voltage rating must be greater than or equal to the circuit voltage, open quickly, extinguish the arc, and prevent re-striking.

Current Ratings
Fuses are marked with a nominal current rating. Factors affecting this include clip material, conductor size, and installation quality.

Breaking Capacity
A fuse must safely open the circuit under a short circuit without endangering surroundings.

Fuse Resistance
In most applications, the voltage drop across a fuse is negligible, but in critical applications, fuse resistance must be considered.

Glossary of Terms
Includes terms like I2t, arc time, operating time, fast fuses, overcurrents, overloads, ohmic load, RMS current, short circuit, delayed fuses, and nominal voltage.

Ambient Air Temperatures
Standardized tests are performed at 23°C and 25°C. Adjustments should be made for higher ambient temperatures.

Electronic INFORMAZIONI GENERALI General Information Informations Générales ¡ Tecnologia di base dei fusibili I fusibili in miniatura servono a due scopi principali: a) per proteggere componenti, apparecchiature e persone dal pericolo di incendi e shock causati da sovraccarichi di corrente. b) per isolare dei sotto sistemi dal sistema principale quando si verifica un guasto. ¡ I sovraccarichi I sovraccarichi si verificano quando viene superato il carico di corrente normale di un circuito. Può essere sia un sovraccarico che un corto circuito. Un sovraccarico è un qualsiasi flusso di corrente che...

¡ Basic Fuse Technology Miniature fuses serve to two main purposes: a) to protect components, equipment and people from risk of fire and shock risk caused by overcurrents. b) to isolate subsystems from the main system once a fault has occurred. ¡ Overcurrents Overcurrents exist when the normal load for a circuit is exceeded. It can be either an overload or short circuit. An overload is any current flowing within the normal circuit path that is higher than the normal circuit full load current. A short circuit is an overcurrent which greatly exceeds the normal full load current of the circuit....

Electronic INFORMAZIONI GENERALI General Information Informations Générales ¡ Corrente nominale Ogni fusibile è marcato con una corrente nominale. Diversi fattori possono influire sulla capacità del fusibile di portare la sua corrente nominale. In primo luogo il materiale della pinzetta/clip su cui il fusibile è montato può interferire con la prestazione del fusibile. Un altro fattore importante è la misura del conduttore usato per connettere il fusibile agli altri componenti del circuito: se il conduttore è troppo piccolo genera calore. Il fusibile sente il calore extra e si apre in anticipo....

¡ Current ratings Each fuse is marked with a nominal current rating. Several factors can affect the ability of the fuse to carry this rated current. First the base material of the clip in which the fuse is mount-ed may greatly affect the performance of the fuse. Another important factor is the conductor size used to connect the fuse to other circuit components. If the conductor is too small, it will generate heat. That extra heat will be seen by the fuse, causing the fuse to open before it should. It is also important that the fuse be installed with clean and tight connections. If the connections...

Electronic GLOSSARIO Glossary of terms Glossaire ¡ Quadrato del valore della corrente moltiplicato per il tempo I2t Si tratta della quantità di calore fornita a un circuito nel momento in cui il fusibile interviene su un guasto. Si può esprimere coi termini “I2t di fusione”, “ I2t dell’arco” oppure la somma dei due detta “ I2t di interruzione”. Questa è solitamente usata come misura di attuazione di un corto circuito. ¡ Tempo di arco È il periodo di tempo che intercorre tra l’istante di fusione del fusibile e il momento in cui il sovraccarico è interrotto. ¡ Tempo di intervento È il periodo di...
