Through Hole Resistors

The WW1BT250R is a through-hole resistor that can be used in a variety of applications and settings. It is a non-inductive resistor that is used for grounding, surge protection, current-limiting, and many other applications. The resistors are constructed with a single-leaded ceramic body. The leaded end of the resistor is designed to fit into an appropriate hole on a printed circuit board (PCB) and the other end is soldered onto the board. The resistor is mainly used in current-limiting applications, such as in AC power supplies, motor controls, and industrial equipment.

The WW1BT250R resistor is rated for a DC voltage of 1000 V. It has a nominal resistance value of 250 Ω and a tolerance of ±5%. The power dissipation of the resistor is 2 W and the operating temperature range is -55°C to +125°C. The physical dimensions of the resistor are 2.4 mm in diameter and the total length is 5 mm.

Application Field

The WW1BT250R through-hole resistor can be used in a variety of applications. These include motor control, AC power supplies, industrial equipment, circuit protection, and surge protection. For example, the resistor can be used in the motor control applications to limit the motor\'s current draw. It is also used in AC power supplies to prevent the power from being overloaded, and in industrial equipment to protect sensitive components from voltage spikes.

Working Principle

The working principle of the WW1BT250R resistor is based on Ohm\'s law, which states that the current flowing through a resistor is inversely proportional to its resistance. When a voltage is applied across the resistor, it will produce a certain amount of electrical resistance, based on its nominal resistance value. This resistance restricts the current through the resistor, which prevents the circuit from being overloaded.For example, in an AC power supply circuit, the resistor will limit the current that is supplied to the load. This will help to avoid damage to the circuit caused by an overload. Additionally, the resistor can be used in motor control applications to protect the motor from overcurrent. The resistor will act as a current limiter and will restrict the amount of current flowing through the motor.

Conclusion

The WW1BT250R is a through-hole resistor that is used in a variety of applications for current-limiting, surge protection, grounding, and more. It is constructed with a single-lead ceramic body and has a DC voltage rating of 1000 V, a nominal resistance value of 250 Ω, and a tolerance of ±5%. It is primarily used in AC power supplies, motor control applications, and industrial equipment to protect the circuit from overcurrents. The working principle of the resistor is based on Ohm\'s law, and it acts as a current-limiting device to prevent circuits from being overloaded.
