I've used this set to make many connections on my amateur radio mobile and fixed stations. Great quality and value. Don't hesitate to buy this set!!

Good selection and quality of components.

The BOJACK Metallized Polypropylene Film DC Capacitor Assortment Kit includes 15 different capacitor values, totaling 150 pieces. Designed for high-voltage DC circuits, this assortment covers a wide range of capacitance (400V: 0.01uF ~ 0.56uF; 630V: 0.001uF ~ 0.068uF). Tested in various electronics projects and repairs, these capacitors performed reliably in audio, power supply, and filtering applications.Pros:✅ Wide Value Range: Covers a variety of capacitance values, making it suitable for diverse projects and repairs.✅ High Voltage Ratings: 400V and 630V ratings ensure compatibility with high-voltage DC circuits.✅ Durable and Reliable: Metallized polypropylene construction offers excellent stability, low loss, and high insulation resistance.✅ Well-Organized Packaging: Each value is neatly separated and labeled, simplifying selection and storage.✅ Cost-Effective Kit: Provides a comprehensive set of components at an affordable price.Cons:❌ Limited Capacitance Range for Low-Voltage Applications: Not ideal for projects requiring higher capacitance at lower voltage ratings.❌ Short Leads: Leads are adequate for PCB work but may feel short for breadboarding or manual soldering in larger circuits.Performance and Usability:During testing, the capacitors demonstrated excellent stability and low loss in filtering and timing circuits. Their high insulation resistance ensured reliable performance in high-voltage scenarios. The labeled packaging streamlined the selection process, saving time in assembly work. However, the short leads required careful handling when used outside of PCB-mounted applications.Comparison:Compared to ceramic or electrolytic capacitors, the BOJACK Metallized Polypropylene Film Capacitors excel in stability, durability, and low noise. While other kits may offer broader ranges of capacitance or voltage, this assortment specializes in high-voltage DC applications, making it more focused for such needs.Who Is This For?:This kit is perfect for hobbyists, repair technicians, and professionals working on high-voltage DC circuits, audio equipment, or power supplies. It’s especially suitable for those needing reliable, low-loss capacitors for precise applications.Conclusion:The BOJACK Metallized Polypropylene Film DC Capacitor Assortment Kit is a reliable and comprehensive set for high-voltage electronics work. While the lead length may be a minor limitation, the range of values, quality of components, and organized packaging make it an excellent addition to any electronics toolkit.

Good bargain for the capacitors.

Good selection of values, great for the home radio repairer.

I tested a number of these using an Analog Discovery 2 with impedance analyzer module.Here are some measurements, all taken at 100 KHz:The 0.56 uF caps have ~5% variation in capacitance and an ESR of ~61 mΩ.The 0.22 uF caps have ~2% variation in capacitance and an ESR of ~49 mΩ.The 68 nF caps have ~1% variation in capacitance and an ESR of ~25 mΩ.These ESRs and tolerances may not beat name brand caps from the likes of Cornell, Nichicon, Kemet, or Würth, but they are perfectly acceptable for the majority of hobby projects and small electronics repairs.For reference, 10% capacitance variation and an ESR of 100 mΩ or less is more than sufficient for most applications.I don't have the equipment to test the voltage ratings, but given the results above I trust the listed values.

I like to tinker with the pots/caps in my guitars and basses. This polypropylene capacitor kit offers a good range of values for both tone caps and treble bleed circuits. Orange Drops aren’t crazy expensive, but their cost can add up over time. They also tend to be kind of bulky. The caps in this kit do the job just as well. Being polypropylene, they should have a little better tolerance than ceramic for this application. As an added bonus, they look very similar to the capacitors Fender packages with their potentiometer kits.
