Frequently Asked Questions
Q: What is the difference between PT0603, PT0805, and PT1206 photoresistors?
A: These designations refer to the physical size (footprint) of the SMD component. PT0603 is the smallest (1.6mm × 0.8mm), PT0805 is mid-size (2.0mm × 1.25mm), and PT1206 is the largest (3.2mm × 1.6mm). Choose based on your PCB pad layout and ease of soldering — PT1206 is the easiest to hand-solder, while PT0603 suits fine-pitch automated assembly.
Q: Are these photoresistors compatible with Arduino and Raspberry Pi projects?
A: Yes! These SMD photoresistors can be used in Arduino, Raspberry Pi, and other microcontroller-based projects, typically in a voltage divider circuit. They are excellent for reading ambient light levels and triggering automated responses in your circuits.
Q: Are these components RoHS compliant?
A: Yes, these SMD photoresistors are environmentally friendly and RoHS-compliant, meaning they are manufactured without hazardous substances such as lead, making them safe for use in consumer and commercial electronics applications.
Q: How many pieces are included in one pack?
A: Each pack contains 10 pieces of SMD photoresistors. You can select the footprint size (PT0603, PT0805, or PT1206) that best fits your project when adding to cart.
