Frequently Asked Questions:

Q: What is the physical size or lead pitch of these 1/2W resistors?
A: Standard 1/2W carbon film resistors typically have a body length of approximately 9mm and a diameter of 3.5mm, with lead pitches suitable for standard through-hole PCBs.

Q: Can these 47k Ohm resistors be used in high-frequency circuits?
A: Carbon film resistors are generally suitable for general-purpose applications. For high-frequency circuits, metal film or specialized RF resistors may offer better performance due to lower parasitic inductance and capacitance.

Q: What is the maximum voltage these 1/2W resistors can safely handle?
A: The maximum working voltage for a 1/2W carbon film resistor is typically around 350V to 500V, but it is crucial to ensure the power dissipation (I²R or V²/R) does not exceed 0.5W.

Q: Are these resistors suitable for replacing 47k Ohm metal film resistors?
A: These carbon film resistors can replace metal film resistors if the application's tolerance (±5% vs. typically ±1% for metal film) and noise requirements are met. Carbon film resistors generally have higher noise characteristics.

Q: How many 47k Ohm 1/2W resistors are included in one pack?
A: Each pack contains 5 individual 47k Ohm 1/2 Watt Carbon Film Resistors (CFR).
