Through Hole Resistors
RWM0622R330JA15E1 is an axial lead resistor with a 15 watt power rating. It is the perfect choice for applications where medium size components are required and moderate power dissipation is needed. The resistor has a small case size making it ideal for through-hole applications. This resistor is designed for general purpose and commercial applications, providing a reliable and stable performance.
Application Field
A few applications where RWM0622R330JA15E1 can be used include audio crossover networks, power supplies, DC/DC converters, inverters, and regulation circuits. Its 15 watt power rating makes it suitable for use in amplifiers, oscillators, switching power supplies, and power transistors as a protective device. RWM0622R330JA15E1 also can be used in the aerospace and defense markets, in aerospace equipment that employ precise voltage regulation.
Working Principle
The working principle of the RWM0622R330JA15E1 resistor is based on the fact that an electrical current passing through a resistor will generate a voltage drop. This voltage drop is proportional to the amount of current traveling through the resistor. Essentially, the resistor acts as a load, dissipating electrical joules in the form of heat energy. This heat energy is what prevents the current from overloading components on the circuit.
The resistor is composed of a metal wire which is wound around a cylinder-like body. This winding of the metal wire determines the amount of resistance in the resistor. The more winding, the higher the resistance value. It is important to keep in mind that the higher the resistance, the lower the current flowing through the resistor and the less heat it will generate.
The most common type of material used to construct resistors is carbon-film. This is because carbon-film is relatively inexpensive and provides superior temperature stability compared to other materials. Carbon-film resistors are designed to able to handle a wide operating temperature range.
To properly install a RWM0622R330JA15E1 resistor, use the following steps as guidelines:
- Attach two short lengths of silicone tubing at each end of the resistor
- Using a soldering iron, heat up the two pieces of tubing and then attach the resistor components
- Heat the resistor until it has been properly attached
- Using strain reliefs, attach the two pieces of tubing and the resistor to the circuit board
- Using insulation tape, wrap the resistor and connections
- Once the insulation is in place, the resistor is ready for connecting to other components on the circuit board
RWM0622R330JA15E1 resistors are great choices for medium size components needed in through-hole applications. They are reliable, stable, and affordable. Thanks to its 15 watt power rating, this resistor can be used in a variety of applications from audio crossover networks to aerospace equipment. With the right installation technique, this resistor can provide years of reliable service.
