5K 3386P Trimpot (Pack of 5)
Trimmer Potentiometer (Trimpot)
A 5K 3386P Trimpot is a type of precision potentiometer designed for circuit boards and electronic devices. Its primary function is to allow for precise adjustments of electrical resistance within a circuit. This trimmer potentiometer is a variable resistor that enables users to accurately set and fine-tune the resistance values in their designs.
This product is sold in a pack of 5 pieces, making it an economical option for designers and developers who require multiple trimmer potentiometers for their projects.
Before using the trimpot, ensure the circuit is powered down to avoid any damage or electrical shock.
Cleanliness and handling precautions should be taken to maintain the component's performance and longevity.
Soldering should be done in accordance with the manufacturer's recommended guidelines.
Component Documentation: 5K 3386P Trimpot (Pack of 5)OverviewThe 5K 3386P Trimpot is a 5k, 3386P-style, rotary trimpotentiometer designed for precision adjustment of circuit voltage. This component is ideal for laboratory, prototype, and production applications where accurate voltage division is necessary. The trimpot is supplied in a pack of 5 units.Pinout and PackageThe 5K 3386P Trimpot has a standard 3-pin package with the following pinout:Pin 1: Counter-clockwise terminal (CCW)
Pin 2: Wiper terminal (W)
Pin 3: Clockwise terminal (CW)Key SpecificationsResistance: 5k
Tolerance: 10%
Power rating: 0.5W
Operating temperature range: -20C to +70C
Rotary travel: 330Code Examples### Example 1: Voltage Divider Circuit with ArduinoIn this example, we'll use the 5K 3386P Trimpot to create a voltage divider circuit with an Arduino board.Circuit DiagramConnect Pin 1 (CCW) to GND
Connect Pin 2 (W) to analog input A0 on the Arduino board
Connect Pin 3 (CW) to VCC (e.g., 5V)Code
```c
const int potPin = A0; // Pin connected to trimpot wiper
int potentValue = 0;void setup() {
Serial.begin(9600);
}void loop() {
potentValue = analogRead(potPin);
Serial.print("Trimpot value: ");
Serial.println(potentValue);
delay(50);
}
```
In this example, the trimpot is used to divide the voltage between GND and VCC, and the wiper terminal is connected to an analog input on the Arduino board. The Arduino code reads the analog value from the trimpot and prints it to the serial monitor.### Example 2: Adjustable Brightness Control for an LED with Raspberry PiIn this example, we'll use the 5K 3386P Trimpot to control the brightness of an LED connected to a Raspberry Pi.Circuit DiagramConnect Pin 1 (CCW) to GND
Connect Pin 2 (W) to the PWM pin (e.g., GPIO 18) on the Raspberry Pi
Connect Pin 3 (CW) to VCC (e.g., 3.3V)
Connect the LED between the PWM pin and GND, with a 220 resistor in seriesCode
```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT) # PWM pinpwm = GPIO.PWM(18, 50) # 50 Hz PWM frequencytry:
while True:
for dc in range(0, 101, 1): # 0 to 100 duty cycle
pwm.ChangeDutyCycle(dc)
time.sleep(0.01) # 10 ms delay between duty cycle changes
trimpot_value = int(input("Enter trimpot value (0-100): "))
if trimpot_value >= 0 and trimpot_value <= 100:
pwm.ChangeDutyCycle(trimpot_value)
else:
print("Invalid trimpot value. Please enter a value between 0 and 100.")
pwm.stop()
except KeyboardInterrupt:
pwm.stop()
GPIO.cleanup()
```
In this example, the trimpot is used to adjust the duty cycle of the PWM signal generated by the Raspberry Pi, which in turn controls the brightness of the LED. The user can input the desired trimpot value (0-100) to set the LED brightness.Please note that these examples are for illustrative purposes only and may require additional circuitry or modifications to suit specific application requirements.
