Through Hole Resistors typically come in one of two forms: fixed and variable. Both have one common trait: the resistive element is enclosed in a cylinder, with leads protruding for attachment to a circuit. The UB3C-0R3F1 is a surface-mounted fixed resistor, designed to effectively resist electrical currents in a variety of applications.

The UB3C-0R3F1 is composed primarily of a resistive element and a pair of copper alloy leads that attach to an insulated body. The resistance of this specific resistor is 0.3 ohms, but can range from 0.2 to 10 ohms. It is encased in a small black rectangular housing, measuring 12.5mm long by 6.3mm wide by 8mm tall, and is rated to handle power ratings of up to 6 watts. It is highly temperature- and vibration-resistant, and rated to operate over a -55°C to +125°C temperature range. Additionally, it is certified by Underwriters Laboratories (UL) for safety, adding another layer of reliability.

In terms of its application field, the UB3C-0R3F1 is designed to resist specific amounts of electrical current, making it ideal for power management, overcurrent protection, and load balancing purposes. It is commonly used in electronic devices such as vehicle computer systems, power supplies, smartphones, LED bulbs, and signal amplifiers.

The UB3C-0R3F1\'s working principle is based on Ohm’s Law. This law states that when a current is applied to a resistor, a voltage is produced across the resistor in an amount proportional to the amount of current. In other words, the voltage is directly proportional to the current, and the resistance is constant. By connecting a resistor in series with an electrical load, the current flowing in the circuit is limited by the resistance of the resistor, thus subsequently limiting the amount of voltage and power.

The UB3C-0R3F1\'s resistance can be adjusted to meet the needs the specific circuitry it is being used in. This is possible because the resistance of the resistor will vary depending on the amount of current it is subject to. This means that when a certain amount of current is applied to the resistor, the resistance of the resistor will change slightly. This can be used to fine-tune the amount of power being applied to the connection, allowing the designer to adjust the resistance as needed for optimal performance.

In summary, the UB3C-0R3F1 is a surface-mounted fixed resistor, composed primarily of a resistive element and a pair of copper alloy leads that attach to an insulated body. It is used in a variety of applications, such as power management, overcurrent protection, and load balancing, and is most commonly found in electronic devices such as vehicle computer systems, power supplies, smartphones, LED bulbs, and signal amplifiers. Working on the principle of Ohm’s Law, it is designed to resist a certain amount of electrical current by limiting the voltage and power available to the connection. The UB3C-0R3F1 is highly temperature- and vibration-resistant, and is backwards compatible with several standard electronics mounting systems.
