Passive Diaphragm Radiator Speaker Accessories Showcase Speaker Repair Parts
[Passive Radiator] Product Description: Model: 88 48 Low Frequency Vibration Plate Type: Sound film, diaphragm Material: Rubber Size: 88*48mm Net weight: 35 grams The bass radiator is also called a passive speaker. It is used to replace the inverted tube. The subwoofer made with the radiator has the following advantages compared with the traditional inverted subwoofer. The low frequency diving depth is equal to the back type, but the speed is the same. In this sense, it is faster than the inverted type, using the advantage of a certain closed box, and at the same time completely eliminating the disadvantage of the inverted structure-that is, the wind noise brought by the inverted nozzle.

IC 7805 TO-220 Linear Voltage Regulator LM7805 Made ST
[Voltage Regulator IC] LM7805 5V Linear Voltage Regulator IC 7805 The L78M05CV is a fixed output, three-terminal precision positive voltage regulator in 3 pins TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single-point regulation. The L78M05CV fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short circuit protection that limits maximum current the circuit will pass and output transistor safe area compensation that reduces the output short circuit as the voltage across the pass transistor is increased. If adequate heat sinking is provided then this positive voltage regulator can deliver over 0.5A output current. Features: Fixed output voltage is 5V Output current is 0.5A Dropout voltage is 2V Maximum DC input voltage is 35V Output transition SOA protection Output voltage tolerance is 4% Operating temperature range 0°C to 125°C Applications: Power Management.

Crocodile Alligator Clip 50 mm Black and Red
Description: An alligator clip, also called a spring clip, creates a temporary electrical connection using a simple mechanical design.It gets its name because the jaws resemble an alligator or crocodile’s mouth, opening and closing to grip objects securely.The clip works like a spring-loaded clothespin that uses tapered, serrated jaws to hold wires or metal parts tightly.A spring pushes the jaws together, allowing the clip to grip objects and maintain a reliable electrical connection.Manufacturers design these clips for electronics testing, enabling quick connections without soldering or permanent joints.One jaw usually connects to a wire by crimping or soldering for efficient current transfer.Some clips use a bent jaw forming the inner contact of a 15 mm to 4 mm female banana jack.This design allows a fast, non-permanent connection between test circuits and laboratory instruments.A plastic cover or boot surrounds the clip to prevent short circuits and protect users from accidental shocks.Engineers and students use these clips widely in testing, prototyping, and educational experiments. Applications: Technicians use small clips (15 mm–40 mm) in electrical laboratories, schools, and college labs for quick test connections.Large clips, called automotive clips or battery clamps, use solid copper for low resistance and strong current flow.Users connect these large clips with thick insulated copper cables between automobile batteries or heavy electrical systems.Hobbyists and professionals rely on these clips for safe, reusable, and efficient electrical connections. Product Example: Check the Crocodile Alligator Clip 50 mm – Red and Black, made from durable stainless steel with a protective plastic shroud.Its spring-loaded jaws open wide to grip different wire sizes securely during testing or circuit connection.The serrated teeth ensure a strong, slip-free grip that maintains stable electrical contact during operation. Package Includes: 1 × Crocodile Alligator Clip 50 mm (Black and Red)
