Feature:1. Suitable Types: XL IC chips assortment kit contains a variety of useful IC types such as opto couplers, timers, oscillators, dual op amps, quad op amps, comparators, sound amplifiers, processors, current mode controllers, arrays, voltage charge pumps.2. Opto Coupler: This type of IC chip is a device that converts optical signals to electrical signals or electrical signals to optical signals. They usually consist of photoelectric converters and electronic amplifiers, which can realize the functions of isolation and antiinterference.3. Plastic Storage Box: Our XL IC chips are sorted accordingly in labeled plastic storage boxes for easy access. Practical and safe.4. Timer and Oscillator: These IC chips are timing and oscillation devices commonly used in electronic systems, which can generate stable electrical signals and periodic waveforms. Timers are often used in applications such as delay and timing, while oscillators are commonly used in circuits such as clocks and counters.5. Dual Opamp and Quad Opamp: These IC chips are commonly used as analog signal processor devices. A dual opamp has two independent opamps that can perform functions such as signal amplification, filtering, integration, and differentiation. Quad opamps have four opamps and can be used for more complex signal processing applications.Specification:Item Type: XL IC Chip Assortment KitMaterial: SiliconIC Category Including: PC817, ICL7660S, NE555, LM358, LM324, JRC4558, LM393, LM339, NE5532, LM386, TDA2030A, TDA2822D, PT2399, UC3842AN, UC3843AN, ULN2003AN, ULN2803APGSocket Category Including: DIP4 socket, DIP8 socket, DIP14 socket, DIP16 socket, DIP18 socket, DIP8 SOP8 converter.Package List:17 x Socket1 x Converter132 x Chip1 x Storage Box
